A PROCESS FOR THE POLYMERIZATION OF AN OLEFINIC HYDROCARBON WHICH COMPRISES CONTACTING SAID HYDROCARBON AT A POLYMERIZING TEMPERATURE IN THE RANGE OF FROM ABOUT 0* TO ABOUT 300*C. AND A PRESSURE IN THE RANGE OF FROM ABOUT ATMOSPHERIC TO ABOUT 200 ATMOSPHERE WITH A SUBSTANTIALLY ANHYDROUS CATALYST PREPARED BY IMPREGNATING A REFRACTORY INORGANIC OXIDE SUPPORT WITH A PHOSPHORIC ACID, AND HEATING THE RESULTING PHOSPHORIC ACID-CONTAINING COMPOSITE WITH A COMPOUND CONTAINING OXYGEN AND SULFUR SELECTED FROM THE GROUP CONSISTING OF SULFURIC ACID, SULFUROUS ACID, AND SULFATES AND SULFITES OF AMMONIUM, ALUMINUM AND METALS OF GROUPS VI-B AND VIII OF THE PERIODIC TABLE AT A TEMPERATUE OF FROM ABOUT 300*C. TO ABOUT 600*C. TO CHEMICALLY COMBINE SAID COMPOUND WITH THE PHOSPHORIC ACID PORTION OF SAID COMPOSITE.
